Send a coding task to Devin (a separate autonomous coding agent) and return its full response. Devin keeps context across calls for the same working directory, so follow-up calls can refer to earlier work. Use for self-contained work you want done in parallel; state the task and the acceptance criteria explicitly, since Devin cannot ask you questions.

Kill the running Devin agent and discard its conversation context. The next devin_task starts a fresh session. Use when Devin is stuck or the context is polluted.
